Growing Renewable Energy in the Midwest

Together with partners around the Midwest, we are expanding access to solar and renewables. We offer one of the country’s top solar training programs and run one of the largest grassroots sustainability events in the nation.

Powered by an assortment of renewable energy systems, our Renew the Earth Institute (REI) in Custer, Wisconsin is our headquarters and primary training facility. At the REI, we offer hands-on courses, give tours, and host The Energy Fair. The building and grounds are available for event rentals like weddings, meetings, and more. Learn more
